SPECIFICATION formingpart of Letters Patent No. 590,764, dated September 28, 1897.

v Application filed May 21, 1897. Serial No. 637,5 77. (No model.)

To all whom, t may concern:

Be it known that we, WILLIAM B. LINDSAY and WILLIAM E. TONNER, residing at Steubenville, in the'connty of Jefferson and State of Ohio, have invented a new and useful Filter, of which the following is a specification.

This invention relates generally to filters, and more particularly to that class of filters known as porous Wall, and is in the nature of an improvement upon the subject-matter of our Patent No. 584,732 l The object of our invention is to provide an exceedingly cheap, simple, and efficient be kept on hand.

Another object is to provide a tubular connection between the reservoir and filteringcylinder.

Another object of the invention is to provide a filter from Which filtered or unfiltered water can be drawn at will.

Vith these various objects in view our'invention consists, essentially, in the employment of a cylindrical casing preferably composed of drawn metal and provided with a cast-metal base anda removable top and porous filtering-cylinder arranged eccentricallywithin the casing, and a cleaner arranged between the filtering-cylinder and casing Aand adapted to be projected against said cylinder by the unfiltered water whenever desired.

The invention consists also in the peculiar.

construction and arrangement ofv the tube, whereby the eccentric arrangement of the iiltering-cylinder is attained; andthe invention consists also in providing suitable guides for insuring a positive movement of the cleaner.

The invention consists also in providing suitable Outlets within the base, by means of which iilteredor unfiltered water can be drawn from the cylinder. y

rlhe invention consist-s also in certain details of construction and novelties of combination, all of which' will be ,fully described hereinafter and p ointed out lin the claims.

In the drawings forming a part of this specification, Figure l is a perspective view of a iilter constructed in accordance with our invention, the reservoir attachment being connected thereto. Fig. 2 is a detail sectional view of said filter with the reservoir. Fig. 3 is a detail sectional View of the iilter without the reservoir, 'the `ltering-cylinder being shown in side elevation. Fig. 4t is avertical section on the line 44 vof Fig. 3. Fig. 5 is a detail perspective view of the cleaner. Fig. 6 is a horizontal section on the line 6 6 of Fig. 8. Fig. 7 is a horizontal section on the line 7 7 of Figs. 2 and 3, and'Fig. 8 is an inverted botv tom plan View o f the top.

In the practical vembodiment of our invention we employ an youter cylindrical casing A, which in practice is preferablyconstructed of a drawn-metal tube, said casing being provided with a'cast-metal base B, which has an opening B inthe bottom thereofv leading into the passage B2, in which is arranged a cock or faucet B3 and by means of which uniiltered water can be drawn from the casing whenever desired. An opening B4 is produced in the bottom of the base to one side ofthe center and communicates with the passage B5, in which is arranged-a cock or faucet B6, through which filtered Water is drawn, as more clearly shown and explained hereinafter. The opening B4 is provided with shoulders B7, upon which rests a central tube O, passing entirely through the ltering-cylinder D, and adjacent to the bottom of the tube O is arranged a washer O', which fits upon'the countersunk portion of the opening B4, thereby providing a' tight joint, inasmuch as the pressure of the water Within the cylinder will always hold the said washer tight upon its seat.

IOO

mit the water passing through the porous cylinder to collect within the central tube. This tube C is securely connected with the porous cylinder by means of the nuts C3 at the top and bottom, and at its upper end lthe tube passes eccentrically through a cap-piece E, which is secured upon the top of the casing by means of a clamping-ring F, and at the upper end of the tube C is arranged a multiple cock G, having a discharge-spout G, and provided with a valve of such construction that the water can be cut on or off, as desired, or it can be permitted to flow up into the reservoir H, which is screwed upon a nipple II', projecting' upwardly from the cock G, as most clearly shown in Fig. 2. When the reservoir I-I is not used, the nipple II is closed by means of a solid cap H3, as most clearly shown in Fig. 3.

I indicates a water-supply pipe which is constructed with an enlargement I and enters the casing A about midway its height, and located in said pipe where it enters the casing is a tubular piston K, attached to a plate K,which securely holds the cleaner L by means of the lugs K2, bent around the sides of the cleaner, as most clearly shown in Fig. 5, and it will of course be understood that any other means of connecting the plate K and cleaner can be adopted, if desired.

The tubular piston K entirely occupies the suppl y-pipe where it enters the casing and is provided with a discharge-opening M in the top thereof through which the water passes into the filter, said water being sprayed upwardly against the top of the filter aud then permitted to iiow down the sides of the filter medium, thus .expediting the filtering.

Parallel guides N, cast integral with the top E, depend therefrom and serve to guide the movement of the cleaner as it is moved back and forth by hydraulic pressure, and we also prefer to arrange guide-pins N uponv the interior of the casingA, as most clearlyshown in Figs. 3 and 4, in order to guide the movement of the cleaner, as before mentioned.

By arranging the filtering-cylinder eccentrically within the casing we are enabled to use a drawn-metal tube for the casing and are also enabled to use a larger ltering-cylinder and at the same time provide ample room for the cleaner.

providing the reservoir upon the top of the filter a definite quantity of filtered water canfalwaysbe had in cases of emergency, but for all practical purposes our filter will perform the filtering operation with such rapidity as to fulfil all ordinary household necessities.

In operation the filtering-cylinder is arranged within the casing after the cleaner has been properly adjusted, the cap set in place and clamped down by means of the clamping-ring. The reservoir can be attached or not, as desired. The lter is then connected with the water-main and water permitted to flow therein. The water quickly passes through the filtering-cylinder and accumulates within the central tube and also within the reservoir and can be drawn off either through the discharge-cock Gl or through the cock B6, as preferred. Should unfiltered water be desired at any time, it can be drawn o through the cock B3, as before described.

In order to clean the filter, the cock B3 is opened and the cock G closed, and the pressure of the water immediately forces the cleaner against the filtering-cylinder, and by revolving the cylinder two or three revolutions by either the reservoir or cock G all sediment is immediately removed from the exterior surface of the filtering-cylinder and drawn out through the cock B3.

- In case the reservoir is used an additional cleaning can be had by cutting off the pressure from the main opening, the cock G permittin g the water contained within the reservoir to flow back within the tube C and out through the filtering-cylinder into the casing and out through the cock B3. In this manner not only the exterior surface of the filtering-cylinder is cleaned, but the entire filtering-stone. The guides always insure the positive action of the cleaner.

It will thus be seen that we provide an exceedingly cheap, simple, and efficient construction of filter and one which can be thor oughly cleaned without removing any parts of the filter or interfering in any manner whatsoever with its operation.

It will also be seen that we provide a filter which permits either filtered or unfiltered water to be drawn from the main.

In practice we prefer to use a natural-stone filtering medium and a natural-stone cleaner, but it will of coursebe understood that it is within the scope of our invention to use the filtering-cylinder and cleaner of any material whatsoever.

By means of the tubular connection be tween the filtering-cylinder and reservoir the filtering-cylinder can be revolved by simply turning the reservoir, and this tubular connection is one of the essential features of our invention.

I-Iaving thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
